Published an op-ed for @cnn.com: “Nobel laureate: I owe America my success. Today, its scientific future is in danger.”
A personal reflection on what’s at stake as science funding gets slashed. I’d be grateful if you could amplify both in and beyond the science world.

Yeah, this was a real headache, and was the impetus for writing the pairwise program. Alignment success rates also varied based on chemistry (see v9 vs. v10 in supplement). Maybe because some of our reads were shorter than medaka was intended for?

We are satisfied with the results and will use this pipeline until such a time that 100% accurate single molecule Nanopore is achieved. We are now using this in many of our synthetic biology pipelines -- directed evolution, MPRAs, DMS libraries. Hit me up with questions or for help.

Grab serum from virally infected (here, COVID) patients to map and monitor single molecule quasi-species distributions of the circulating genomes (would suggest deeper than MinIon reads, we repeat sample preparation multiple times. GridIon probably best).

Accurately quantify edit distributions from CRISPR/Cas9 genome KO pools.

So what can you do with something like this?

QC your viral preps to detect random-break packaging issues not observable in Illumina sequencing.

We develop:
1. Bootstrap algorithm to benchmark # of clusters needed to give accurate sequences on a per run basis.
2. Our own aligner to overcome tandem repeat issues
3. A Docker-based GUI wrapper for the program.

Issue #3, Origin of Mismatches. We see rare mutations in our sequences. Are they real? Yes, we develop a method to PCR the samples directly and confirm by Sanger. Where are they from, bacterial passaging or PCR? Ran LTE of bacteria and repeated PCR -- both contribute, PCR orders of magnitude more.

Issue #2, Abundance Reproducibility. Is the content of a sample accurately reproduced in the data output? We mixed plasmids of known sequence together in a logarithmic range of concentrations and repeatedly measured the sample demonstrating reproducible, accurate readout of abundances.

Issue #1, Chimeric Molecules. Inevitable oligo contamination between tagging and amplification rounds creates hybrid pairs. How to accurately discard them computationally? Using a deep barcoded template as an internal barcode we observed chimera formation patterns and programmed to filter them out.

This work was led by Adam Zahm and Caleb Cranney in our group. There are lots of unique molecular index (UMI) strategies out there, but both the software packages and ground-truth sequence accuracy validations were severely lacking. So we decided to tackle this problem and deliver a unified solution

Want to Nanopore sequence complex nucleotide populations accurately, at low cost, with QC standards, using a plug-and-play informatics GUI, where you can PCR observed sequences out from your sample and not synthesize them? See our new pre-print!

Signal is a great privacy tool, but it isn’t magic. And even if you’re not discussing war plans in your group chat, it’s a good idea to know the limits of encryption.

Encrypted Messaging Is Essential—But It Isn’t Magic
As recent events have shown, using an encrypted messaging app like WhatsApp or Signal is no privacy panacea.

so you're saying American financial policy decisions should be made to appease and court our least responsible voters? Or that we should pump and dump them like our current President and make them poorer?

The job of Democrats is so clear right now: It's to do everything possible in the next 48 hours to keep the Atlantic story front-burner and make people understand the issues and the stakes. It couldn't be a simpler test of who gets it and who doesn't.
